Add all the ingredients except the chicken into a bowl. Mix until combined to create the marinade.
Put the cubed chicken into a large ziplock bag and add the marinade. Refrigerate the chicken and let marinade for up to two hours.
Heat the grill or pan to medium heat depending on how you want to cook the chicken.
Add the chicken to the grill, being sure to use non-stick spray, and cook on each side for about 4 minutes. If you are using the pan, cook the chicken about 4 minutes each side. When the chicken reaches an internal temperature of 165°F it is finished.
Serve over your favorite veggies and rice or alongside your favorite side dish.
Notes
If you don't want it as spicy, decrease the amount of harissa and increase olive oil and lemon juice.
Serve this chicken on its own or over some veggies and rice.
This marinade would go great on chicken wings and thighs too!
In this bowl I use Cava Tzatziki, that I found at Whole Foods. Like I mentioned Tzatziki can be a really nice balance for the spice.
